It is what is presently implemented. As a consequence (illustrated by this pr), optimize for speed is not obeyed if attribute(cold) is set on. I don't see the interest of that: If I want optimization for speed, I just want it. >From comment #47, I got the impression that the intended behavior is the following: if optimized for size is on (-Os) then it is overridden if the block is marked as "hot" (it is not clear for me that it is !attribute(cold)). From this impression the truth table I expect is the following for optimize_function_for_size_p: "hot" 0 1 -Os 1 0 -O[1-3] 0 0 and not "cold" 0 1 -Os 1 1 -O[1-3] 0 1 as presently implemented. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40106
